APPARATUS FOR COOLING BEER.

SPECIFICATION forming part of Letters Patent No. 414,193, dated November 5, 1889. Application filed December 14, 1887. Serial No. 257,879. (No model.)

To all whom it may concern:

Be it known that 1, JOHN S. COOKE, residing at Chicago, in the county of Cook and State of Illinois, and a citizen of the United States, have invented a new and useful Improvement in Apparatus for Cooling Beer, of which the following is a specification, reference' being had to the accompanying drawing, in which the figure is an elevation, with some of the parts in section, showing the apparatus arranged in a brewery in one form.

The objects of this invention are to improve the construction and operation of the apparatus employed in the process of cooling beer in brewing, as hereinafter more particularly described, and pointed out in the claims.

In the drawing, A represents the mash-tub.

B is the filter, connected with the mash-tub by a pipe a.

O is the kettle, connected with the filter by a pipe I).

' D is the strainer, connected with the kettle by a pipe 0.

E is a force-pump, connected with the strainer by a pipe (Z and with an air-chamber e.

F is a pipe leading from the pump and air chamber for conducting the beer to the cooling apparatus, and having a shut-off valve f.

G is a steam-pipe having a shut-cit valve g, and connected with an extension of the coil of the hot-water tank above the point of connection of the pipe F to such coil, which means above the shut-oft valve f.

H is the coil for the hot-water tank, the exit end of which coil has a shut-off valve h.

I is the hot-water tank, having an inlet 1 through which the discharge end of the coil H passes.

J is a pipe leading from'the coil H and having a shutoff valve j.

K is the conduit surrounding the pipe J, so as to leave a space lo between the pipe and conduit, and communicating with the inlet i for supplying cold water to the tank I.

L is an inclosed receiver having top, bottom, and side walls, with an out-letl in the top, forming an overflow for the froth of the beer, and into which receiver the pipe J leads.

M is a chamber having located therein a series of coils m, formed of small tubes, the

coils being located one around the other and having communication with the receiver L,

and this chamber M is supplied with cold wa- -ter from pipes 01, and has an outlet is leading into the conduit K.

N is a receiver having top, bottom, and side walls, and into which the beer is delivered from the coils m.

O is a Baudclot cooler, onto and over which the beer is delivered by a pipe 0, leading from the receiver N, and from which the beer is conducted to the fermenting-tub (not shown) by a pipe 12, as usual.

The parts represented by the letters A, B, O, D, and E, the hot-water tank with its coils, and the Baudelot cooler are of the usual con: struction, except that the Baudelot cooler requires a less number of coils, and the devices can be arranged as shown or in any other suitable manner, and, as shown, the coolingchamber is located at the top of the brewery;

but such chamber and the hot-Water tank and Baudelot cooler could be arranged lower down at any point desired without detriment to the cooling process.

The mash-tub, filter, kettle, strainer, and

force-pump operate as usual, and from the aforce-pump the beer or wort is carried by the pipe F into the coil H of the tank I, and for this purpose the shut-oft valve fis opened and the shut-ofi valve g of the steampipe G is closed, as is also the shut-off valve h. The hot beer or wort, entering the coil H and passing through such coil, is partially cooled, and the heat extracted is utilized in heating the water in the tank I, by which means a partial cooling of the beer or wort is had and the heating of the water in the tank is accomplished. The beer or wort, after passing from the coil, enters the pipe J, the valve 9' of which is open, and is subjected to the cooling effects of the cold water around the pipe J in the conduit K, and the beer or wort is delivered by the pipe J into the receiver L, and the excess of froth, it any, is carried off by the overflow Z, and from the chamber or receiver L the beer or wort passes through the coils m, and in its passing is subjected to the cooling influence of the cold water in the chamber M, and, inasmuch as the pipes forming the coils m are of small diameter and a number of coils are used, 1 the beeror wort will be delivered. through the chamber by the coils m in small streams, so as to be readily and quickly affected by the cold water. The beer or wort, after passing through the coils m, enters the chamber or receiver N, and is delivered therefrom to and over the Baudelot coil, and the beer or wort, when delivered to and over the Baudelot coil from the cooling devices, will have its temperature reduced to a great extent, as in its passage it is cooled by the coil in the tank I, by the Water in the conduitK, and by the passage through the pipes m in the cold-water chamber M, and by such previous reduction of the heat of the beer or wort it Will be delivered to the Baudelot coil ata reduced temperature, requiring only a small Baudelot coil to complete the cooling process.

.The Water in the tank I can be heated from the coil H by supplying steam to the coil from the pipe G, and when so heated theshut-oif valves f and j are to be closed down and the shut-off valves 9 and hopened, as when steam is used for heating the water in the tank I the beer is not being passed through the cooling devices. The steam can be used for cleaning the coil I and. the chambers L, M, and N and pipes J and 0 and coils m by closing the shut-off valve h and opening the shut-off valve j, and when it is desired to Wash the cooling devices with water the valves 9 h are closed and the valves f j opened, and Water can be forced from the pump E through the pipe F and coil H, pipe J, chambers L and N, coils m, pipe 0, to and over the Baudelot coil, efiectually washing and cleaning these parts.

The Water heated in the tank I is not for distillation purposes, but is used for all purposes for which heated water is used about distilleries, such as for cleaning or Washing purposes and for feed-water for the boiler.

The advantage of having both pipes F and G connecting with the coil H is that the coil of pipe H is not only made a conveyer-pipe for beer, but also a conveyer-p'ipe for steam when the supply of beer is cut off. The advantage of this is that, besides heating the water in the tank I for use in the building, the steam circulating Within the pipe acts as a purifier for the pipe and as a destructive agent for any deleterious matter that may form or accumulate in the pipe. This is important, as germs may very rapidly grow within the pipe in the short time that the pipe is not in operation for the passage of the beer.

The running of the hot beer or Wort through the coil H utilizes the heat to heat the water in the tank Iwhile reducing the temperature of the beer or Wort, and by using a number ofcoils m of small capacity the beer is carriedover a long surface in small streams, thereby receiving the full benefit of the cold water in the chamber M, and this reduction of thetemperature of the beer beforereaching the Baudelotcooler dispenseswith ,theuse of a large and expensive cooler; and it will further be seen that the beer or wort, from the time it leaves the force-pump until it reaches the Baudelot cooler, is carried by an inclosed passage, thus retaining the flavor of the beer or wort and its full strength, and at the same time'no dirt or other foreign substance or material can pass into the beer or wort. The beer or wort can be cooled to a large extent by passing it through the coil H without any water in the tank I, to be delivered directly to the cooling-coils m, and one or more of such cooling-coils can be used, the beer or wort being passed from one cold-Water chamber and coil to another.

The coil H can be dispensed with and'the pipe F be led directly to the receiving-chamfrom the start to .the finish, and by so being the time required for cooling is greatly re duced over the time required by the old openpan process, and with the apparatus any desired reduction of the temperature can he had before reaching the Baudelot coil or cooler.

The overflowl is to be closed by acap, and, if desired, the pipe 0 can be provided with a sh ut-off valve 0, by which the outflow through the pipe 0 can be regulated, and by means of the valve j in the pipe J the flow to the receiving-chamber L can be increased or diminished as required.
